The Sinopharm WIBP COVID-19 vaccine, also known as WIBP-CorV, is one of two inactivated virus COVID-19 vaccines developed by Sinopharm. Peer-reviewed results show that the vaccine is 72.8% effective against symptomatic cases and 100% against severe cases. The other inactivated virus COVID-19 vaccine developed by Sinopharm is the BIBP vaccine (BBIBP-CorV) which is comparably more successful. 1 billion doses are expected to be produced per year.
UB-612 is a COVID-19 vaccine candidate developed by United Biomedical Asia, and Vaxxinity, Inc. It is a peptide vaccine.
A viral vector vaccine is a vaccine that uses a viral vector to deliver genetic material (DNA) that can be transcribed by the recipient's host cells as mRNA coding for a desired protein, or antigen, to elicit an immune response. As of April 2021, six viral vector vaccines, four COVID-19 vaccines and two Ebola vaccines, have been authorized for use in humans.
AWcorna, originally termed ARCoV and also known as the Walvax COVID-19 vaccine, is an mRNA COVID-19 vaccine developed by Walvax Biotechnology, Suzhou Abogen Biosciences, and the PLA Academy of Military Science. In contrast to other mRNA COVID-19 vaccines, such as those by Pfizer-BioNTech and Moderna, this vaccine primarily targets the SARS-CoV-2 receptor-binding domain of the spike protein, rather than the entire spike protein. It is approved for Phase III trials in China, Mexico, Indonesia, and Nepal.
Corbevax is a protein subunit COVID-19 vaccine developed by Texas Children's Hospital Center for Vaccine Development and Baylor College of Medicine in Houston, Texas and Dynavax technologies based in Emeryville, California. It is licensed to Indian biopharmaceutical firm Biological E. Limited (BioE) for development and production.
V-01 is a protein subunit COVID-19 vaccine candidate developed by a subsidiary of Livzon Pharmaceutical Group Inc.
Razi Cov Pars is a COVID-19 vaccine developed by the Iranian Razi Vaccine and Serum Research Institute Razi Cov Pars is a covid-19 vaccine based on recombinant protein, which is being produced by Razi Vaccine and Serum Research Institute, Iran. This vaccine is the first injectable-intranasal recombinant protein corona vaccine.It's the second Iranian COVID-19 vaccine reaching human trials and is currently in phase III of clinical research during which it's compared to the Sinopharm BIBP vaccine.
COVI-VAC is a COVID-19 vaccine developed by Codagenix, Inc. In December 2020, COVI-VAC started a Phase I clinical trial, involving 48 participants. The trial was scheduled to complete in June 2021, with results to be reported by May 2022. On September 29, 2021, Codagenix presented positive phase 1 data for COVI-VAC at IDWEEK2021. Data indicates that COVI-VAC is well tolerated, with no significant adverse events reported and that administration of the intranasal vaccine was immunogenic and capable of blocking nasal replication of the virus with minimal viral shedding, recorded at levels lower than those likely to result in subsequent transmission of COVID-19. Furthermore, COVI-VAC was shown to stimulate both serum and mucosal antibody immune responses.
COVAX-19 is a recombinant protein-based COVID-19 vaccine developed by South Australian-based biotech company Vaxine, in collaboration with CinnaGen, a private company with operations in the Middle East. It is under clinical trial in collaboration with the Iranian company CinnaGen.
COVID-19 vaccine clinical research uses clinical research to establish the characteristics of COVID-19 vaccines. These characteristics include efficacy, effectiveness, and safety. As of November 2022, 40 vaccines are authorized by at least one national regulatory authority for public use:
Noora is a COVID-19 vaccine candidate developed by Baqiyatallah University of Medical Sciences in collaboration with Plasma Darman Sarv Sepid Co. in Iran. Introduced in June 2021, it was announced as having "successfully passed the first phase of its clinical trial" two months later.
S-268019-b is a protein subunit COVID-19 vaccine candidate developed by Shionogi.
LYB001 is a COVID-19 vaccine candidate developed by Yantai Patronus Biotech Co., Ltd.
